Transparent Gypsum var. Selenite heavily with included with Copper. This is an excellent example with evenly distributed Copper throughout the entire specimen. Transparent window of Selenite rising up off a small amount of matrix. Most are simple cleavages without the display presence of this one.

Bright yellow crystals of Smithsonite replacing Dolomite, with the curving form of the former Dolomite crystals clearly evident.
Smaller individual Smithsonite crystals are scattered across the surface of the matrix. The bright color is caused by inclusions of Greenockite.
Beautiful specimen!

Stunning Hematite and Quartz specimen from the classic Arizona locality, likely from the late 1970s. Mirror lustrous tabular crystals to 1.9cm.
Comes with an old Larry Conklin label that shows a price of $550 likely from decades ago. There are some small damaged crystals, still this is by far the
best I've owned or seen, though admittedly I have not seen many - they are uncommon, Mindat only shows 18 specimens.

Classic Arizona specimen with individual cluster of acicular Dioptase crystals and orange Wulfenite crystals. The Dioptase clusters
reach 7mm in diameter. There is an area along one edge of the specimen with more drusy Dioptase and small Cerussite crystals. This is an old specimen
out of a collection.

Outstanding blue Celestite crystals with attached purple Fluorite. Individual crystals reach 5.5cm in size and are highly lustrous, many doubly-terminated.
The specimen is displayable from both sides with great crystallization all around. Old labels indicate it was collected by Tim Elliot in 2002
and traded to Bill Pinch in 2003.

Transparent Morganite crystal with inclusions of Lepidolite and a pink Tourmaline crystal. Purple Lepidolite and pink Tourmaline
wrap around the base and sides. The back and part of the top are contacted. Tourmaline inclusions in Morganite are rare.

Outstanding Butte Enargite with large isolated crystals to 1.6 cm. Choice, quality crystals with accenting small Quartz crystals.
Such isolated crystals are uncommon with the vast majority of Butte Enargite specimens made up of interlocking, drusy crystals.
Would make a superb addition to any Butte or USA collection.

A 1.2cm cube of Byxbyite well centered in Rhyolite. Surrounding the cube are crystals of Topaz, purple Fluorite, and black acicular
crystals of Pseudobrookite. Acquired by Mike Groben in 1980 and pictured in the August 1980 issue of the Lapidary Journal. Appraised years ago at
$1500. Great display specimen and a good combination specimen of most of the important minerals found in this area. He's a chance to own a species that
is normally black and somewhat non-exciting to look at in a vibrant specimen with color and aesthetics.
